Question Front Wheel Brake Locking Up

For the second time in a year, my wife's 2006 PT has had the driver's side front wheel heat up and start smoking. Both times, the pads were worn down and frozen in place. Both times the rotor was trashed and way too hot to touch for an hour, but the caliper seems OK.

Has anyone else had this problem and how did you solve it?

So your saying shoes stuck but caliper is not. That being the case you clean all see faces that the shoe touches on the pad sets in. The should go in by hand and slide back a forth by hand. If not you either find a brand that will or file the pads to the point they will move in the holder Greeley but not flipping around.

Unhappy Re: Front Wheel Brake Locking Up

Right now, my wife and the PT is stuck in another town at a local indy garage. Let's hope they figure this out.

Yes. I've seen this a WHOLE lot on older 1980 and 1990 Chevy trucks. It's almost always the rubber brake line that runs out to the front calipers.

What happens is that the rubber line collapses on itself. When you push on the brake, fluid is pushed through the line to caliper, but it cannot return. So pressure stays on the caliper. Once the pressure leaks off or the brake line is taken lose, the caliper seems to function normally.

I haven't read about this happening on a PT Cruiser. And I've owned Chrysler vehicles for many years and never experienced it on any of them. For me, it's always been GM trucks that did this. But you never know.

If you remove the rubber brake line from the offending wheel, you may be able to tell if it seems blocked.

PS: Today I still own three older GM trucks. And I hate them all! If they weren't cheap and easy to work on, I'd likely burn them.

on this site i read about the front line "clogging" i believe?(what the thread said anyways). someone changed both calipers, rotors, and had new pads but the brake still stuck on the same side in the front just like with the old junk. changed the line per recommendation on here and it was finally fixed. still makes no sense to me though. for all i know it was fixed more by bleeding it more than by changing the parts.

I have this same problem on my 2009 PT. I now realize what my deceased Mother-in-law meant when she stated that the PT didn't have enough power to climb the mountain we live on. I have had this problem also on my 2000 Dakota SLT.

I had this happen to my '01 several times on both front brakes. I replaced both calipers and have had no problems since then. At a later time I flushed all of the brake fluid.

It could be bad rubber lines and or bad calipers.

this has happened to me..in a Dodge Spirit front passengers side rubber brake line was weak and collapsing causing the passenger side front brakes to stick....and wear out the pads ...everything was fine except the rubber lines..

Always clean you brake parts. Keep contaminates off the brake hoses i.e. grease gas chemicals, etc. When rebuilding wheel cylinders or calipers use lots of brake clean and then pressurized air out all the orifices. Never assume a rebuilt caliper is done correctly. Examine it carefully before using it. Always replace the brake fluid in the system with a simple flushing. Takes an extra 1/2 hour labor and a quart of brake fluid, a 6 pack for your buddy to help to with the foot brake action.When the work is all done wash everything done with soap (simple green) and rinse with water. Test drive and recheck for leaks and re-tighten all the fasteners.

I haven't looked at the caliper setup on the pt for a few years, but check the return springs if it has them. Also use synthectic brake grease on the moving points of the pads and where the brake cylinder contacts the pad. Wouldn't hurt to change the fluid and check for rust or dark fluid.
